Answer:
density = 7.55 g/cm^3
Explanation:
we need to get the volume first to get the density , and the volume formula is:
the volume = area * thickness
where :
area = 2 cm * 2 cm = 4 cm^2
and thickness = 100 cm
by substitution:
the volume = 4 * 100 = 400 cm^3
where
density = mass / volume
we have to convert mass from kg to g = 3020 g
by substitution:
density = 3020 g / 400 cm^3
= 7.55 g/cm^3
